Abstract
A radioactive guide instrument type double-casing orientation measuring method for oil and water well oil pipe transmission type perforation dynamic test of an oil field is realized by an aboveground control system and an underground test system, and comprises a large casing, a small casing, a logging cable, a gyroscope, a double-gamma instrument and a radioactive guide instrument; the gyroscope, the double gamma instruments and the radioactivity guide instrument are all connected by logging cables; before testing, firstly, changing the radioactive homomorphic primordium of the double-gamma instrument from the inside of the lower end of the double-gamma instrument to the outside of the instrument, and arranging the radioactive homomorphic primordium into a self-made guide instrument for sealing, and connecting the radioactive homomorphic primordium with a ground control system through a logging cable; connecting a gyroscope and a double-gamma instrument in the combined instrument on the ground through a connector, correcting after connection, and then connecting the gyroscope and the double-gamma instrument with a ground control system through a logging cable; the method solves the problem of poor measurement accuracy of the existing direction finder in the prior art. The invention can be widely used for the transmission type perforation dynamic test operation of oil pipes of oil wells and water wells of oil fields.
Description
Technical field:
The present invention relates to the method for measuring position of radioactive guide instrument type double sleeve that a kind of oil field oil, well tubing conveying type gun perforation dynamic test are used.
Background technology:
In order to dynamic observe the dynamic change situation of steam exploitation block downhole temperature field and pressure field, make monitoring materials real-time, continuous, three-dimensional, long-term, change, understand oil reservoir vapor chamber forming process and steam-front propelling situation so that in time grasp block reservoir temperature field pressure field, the instant measure of adopting of annotating, the raising steam drive reservoir development effectiveness adjusted.The other welding of casing sucker rod is being observed in employing, and sleeve pipe and sucker rod be the lower going-into-well intraocular simultaneously, is lowered to optical fiber and carries out the dynamic monitoring temperature in sucker rod, and the monitoring dynamic pressure has improved single port and block oil well dynamic monitoring level comprehensively in the sleeve pipe.This technology has been implemented many mouthfuls of wells in the Liaohe Oil Field at present,
Because the outer interior requirement of sucker rod of sleeve pipe is lowered to dynamic monitoring equipment such as optical fiber, wear sucker rod if penetrate during perforation, interior and the combination of zones of sucker rod, high-temperature steam can enter sucker rod, not only can have influence on the security seal at well head place, also can shorten the application life of thermometric optical fiber in the sucker rod, so need avoid outer sucker rod during perforation.
When observing the well perforation, heavy oil block require the perforation tunnel can not damage its outside sucker rod.Because the limitation of existing directed Instrument measuring precision, suitable environment, cause the perforation orientation accuracy poor, long construction period, even the part well is arranged owing to the reason of instrument can not be finished construction task, need to be fit to the high directed instrument of precision that heavy oil block is observed well, and according to the phase place of outer sucker rod track azimuth design perforating gun, the high-quality and efficient heavy oil block of finishing is observed the well perforation.
Summary of the invention:
The purpose of this invention is to provide a kind of method for measuring position of radioactive guide instrument type double sleeve, this method has solved the limitation owing to existing finder suitable environment that exists in the prior art, causes the problem of perforation low precision.
The technical solution adopted for the present invention to solve the technical problems is: method for measuring position of radioactive guide instrument type double sleeve: in order to avoid outer sucker rod perforation, at first to measure the orientation track of outer sucker rod, need a kind of new measurement track combination instrument of development, through ground underground trials repeatedly, the final track of determining to use two gamma instrument and the outer sucker rod of gyroscope measurement in a closed series, concrete scheme is to be lowered to the radio isotope guided ware in outer sucker rod, in sleeve pipe, be lowered to two gammas and gyro combination instrument, there are 6 gamma-ray probes that are evenly distributed two gamma instrument inside, when the radioactive isotope power supply in gamma-ray probe and the guided ware is in the same degree of depth, owing to the difference of guided ware with respect to two gamma instrument orientation of living in, the numerical value difference of the record on each probe.The orientation of guided ware is substantially between the maximum probe of two numerical value, one, two probe mid point orientation of gyrostatic guide slot and two gamma instrument are consistent, receive the difference of numerical value and the orientation that the gyro cooperation calculates the outer sucker rod in each depth point by 6 gamma instrument probes on two gamma instrument, through multimetering, draw out the orientation trajectory diagram of the outer small casing of this well, and finally determine the phase place of this well perforating bullet with respect to big sleeve pipe;
This method mainly is achieved through the following technical solutions: first Application gyroscope and gamma instrument are logged well in logging operation, and this method is mainly finished by aboveground control and downhole testing system; The downhole testing system is at first former with the radioactivity of two gamma instrument before well logging, changes into outside the instrument body in the body by two gamma instrument lower end, and sealing is connected with ground control system by logging cable in the homemade guided ware of packing into; The gyroscope that will make up in the instrument on ground is connected by connector with the gamma instrument, proofreaies and correct after the connection, then is connected with ground control system by logging cable; The downhole testing system is made up of logging cable, the small casing of logging well, the big sleeve pipe of logging well, gyroscope, two gamma instrument, radioactivity guided ware, and the equal cable circuit of above-mentioned test component connects; Gyro, two gamma combination instrument are lowered in the big sleeve pipe, under the guided ware in small casing, and depth-logger aimed at zero degree (being zero point), the connection angle of gyroscope and two gamma instrument: being respectively probe 1 and being 330 °, probe 2 and be 30 °, probe 3 and be 90 °, probe 4 and be 150 °, probe 5 and be 210 °, probe 6 is 270 °; When the radio isotope of gamma-ray probe (even cloth 6) and guided ware is former when being in the same degree of depth, because guided ware is with respect to the difference in two gamma instrument orientation of living in, the record numerical value on each probe is difference also during well logging; The orientation of guided ware is substantially between the maximum probe of two numerical value, 1,2 probe mid point orientation of gyrostatic guide slot and two gamma instrument are consistent, receive the difference of numerical value and the orientation that the outer sucker rod in each depth point is planned out in the gyroscope cooperation by 6 gamma instrument probes on two gamma instrument, through multimetering, draw out the orientation trajectory diagram of the outer small casing of this well, and finally determine the phase place of this well perforating bullet with respect to big sleeve pipe.
The invention has the beneficial effects as follows: by using radioactivity guiding ceremony straight well oriented perforating technology, developed a kind of combined instrument of observing borehole measurement sucker rod track orientation at heavy oil block, through ground and underground trials, accuracy that can the confirmatory measurement data, pass through the measurement of this well sucker rod track in addition, tentatively grasped sucker rod track Changing Pattern, for similar well construction after us provides valuable experience.
