A kind of double lance ropes of double hook for coring drilling with keep up pressure of the invention are sent into and the application method of fishing device, including with
Lower step:
(1) it launches salvaged part: salvaged part being connect with running tool part, and is thrown by running tool part
Salvaged part is put, and is sent to bottom hole, is arranged the second fishing spear in the first fishing spear of salvaged part, uses feeding work
Shaft bottom is sent into salvaged part by tool part, and the lower part weight of salvaged part is successively transferred to salvaged part from bullet card pedestal
Second fishing spear, the first fishing spear, running tool recovery hook, running tool part and the first wirerope；
(2) running tool part and salvaged part disengage: launching salvaged part and sit to shaft bottom and block, when salvaged part
When being fed through bottom hole, under effect of inertia, the flexible sliding hammer decentralization in running tool part shrinks hammering off card ring, realizes feeding work
The recovery hook and salvaged the first fishing spear of part for having part disengage, to realize that running tool part and salvaged part are de-
It opens；
(3) it recycles running tool part: recycling running tool part to well head by above mentioning the first wirerope；
(4) it turns round coring: after recycling running tool part to well head by the first wirerope, connecting drilling rod and carry out round trip
Turn round coring；
(5) fishing tool part is combined with salvaged part: after completing round trip coring, drilling rod being removed, and launches and beats
Fishing combined tool part enters in well, under the guidance of fishing tool guide cup, fishing tool recovery hook and the first of salvaged part
Fishing spear connection, while fishing tool guide cup squeezes corer recovery hook, disengages corer recovery hook and the second fishing spear；
(6) it is salvaged part to fetch: lifting the second wirerope at this time, mentioned by fishing tool part and draw salvaged part
First fishing spear above mentions, while off card pipe being driven to move up, and well head is proposed after off card, takes out sample, completes coring drilling with keep up pressure process.
A kind of double lance ropes of double hook for coring drilling with keep up pressure of the invention are sent into the application method with fishing device, the step
Suddenly running tool part with the connection of salvaged part is to be connect by running tool recovery hook with the first spear-head in (1).
A kind of double lance ropes of double hook for coring drilling with keep up pressure of the invention are sent into the application method with fishing device, the step
Suddenly in (4) during revolution coring, bullet card bears the bit pressure of drill bit and offsets the resistance of core sample entrance, so as to convenient
Cooperate coring.
A kind of double lance ropes of double hook for coring drilling with keep up pressure of the invention are sent into the application method with fishing device, the step
Suddenly when off card pipe moves up in (6), bullet card is stretched out outward by off card pipe range sliding slot to be withstood on adapter coupling shoulder, and off card pipe moves up
In the process, bullet card will not recycle off card, until off card pipe range sliding slot bottom is contacted with bullet card, and collapse bullet card, bullet card and bullet card
Stopper off card.
Compared with prior art the invention has the benefit that
1, the present invention controls connection type by the double lances of double hook, realizes the differential movement of two-tube corer, and can lead to
The mode for crossing recovery hook different from two kinds of spear-head elastic off card and connection realizes that corer is the feeding of salvaged part
It is moved with the successive triggering for salvaging internal different institutions；
2, rotary gastight sampling is carried out using the salvaged device of the present invention, can adapt to the 4th is sedimentary formation and base
Rock, application range is wider, and can bear to bore when salvaging coring by the mutual cooperation of bullet card and its suspension mechanism
Head bit pressure simultaneously offset core sample entrance resistance, so as to facilitate cooperation coring, and can be held axially fixed and
Single action effect facilitates and realizes rotary coring, convenient and efficient；
3, the present invention can control connection type by the double lances of double hook, realize the differential movement of two-tube corer；
4, running tool part and fishing tool part and the hook and unhook mode of salvaged part are simple in the present invention
It is convenient, going on smoothly for coring operation is realized so as to facilitate.
