Description
Technical field
It is especially a kind of non-the present invention relates to the display of well head gas during petroleum industry Oil testing and metering device
Flowing well formation testing well head display device and its application method, the gas that can be accurately shown and described in nonflowing well stratum contain
Amount and type.
Background technique
It is existing according to petroleum industry relevant criterion SY/T 6013-2009 " oil test data admission specification " 4.11.4.1.4(test
H) the requirement of clause in data needs to enroll " ground display description (containing oil pressure, casing pressure) " data during formation testing well test.
The description of flowing well ground display at present is usually to be performed such that when formation testing exploratory well has oil/gas show, and be produced from
After spray, three phase separator and open flow process are connected in flowing well well head, oil and gas and water is carried out from counting respectively by three phase separator
The yield for measuring oil gas water describes crude oil, the gas and water yield feelings of pretest exploration activity well by the yield of oil gas water after metering
Condition.
Gas shows that power goes out to understand stratum in the well that the display description of nonflowing well ground is mainly come out by well head
The case where oil gas water.Currently, such as not self-spray, scene is all made of cotton yarn, sebific duct, bucket as tool during test drives a well
It observes, under normal circumstances, cotton yarn is dipped in upper water, wrap survey gas sebific duct one, survey gas sebific duct other end is placed in bucket,
Sebific duct is in water surface depth below and bubbling outlet display situation bucket by observing and measuring by site operation personnel, to measure
The borehole pressure of Pressure Curve in Oil Testing Well.Above-mentioned viewing tool is very simple and crude and lack of standardization, and operation is also inconvenient, affects sight to a certain extent
It is examining and measure as a result, reducing the authenticity of in-situ data.It is easy to be populated with malicious pernicious gas in metal bucket simultaneously, exist certain
Security risk.
For many years, the nonflowing well in Pressure Curve in Oil Testing Well wants more more, ground gas display description inaccuracy more than flowing well
The problem of it is very universal, need to improve.
Summary of the invention
