Abstract
The invention relates to the technical field of oilfield production engineering, belongs to an oilfield open-hole packer horizontal well fracturing well completion method, and aims to solve the problem that: in the conventional common sliding sleeve type staged fracturing well completion process, a sliding sleeve is difficult to open due to the influence of stratigraphic back pressure sometimes. The oilfield open-hole packer horizontal well fracturing well completion method mainly comprises the following steps of: delivering a well completion pipe string to a preset position through a deliver pipe column; delivering a setting pipe column and gradually setting the open-hole packer 4; and when fracturing is needed, delivering a fracturing pipe column to complete all interval fracturing. The oilfield open-hole packer horizontal well fracturing well completion method has the advantages that: the internal drift diameter of well completion is large, the number of treated segments is large, fracturing after delivery can be firstly obtained, and fracturing, acidification, water plugging measures can be performed on any interval and the like.
Description
Technical field: the present invention relates to the oil field technical field of oil production engineering, belong to a kind of oil field open hole packer fractured horizontal well completion method.
Background technology: at present external bore hole pressure break completion adopts the bore hole external packer of pipe to separate the stratum more, and the mode of sliding sleeve pressure break is opened in pitching, but exist sliding sleeve to open difficulty, needs brill mills ball seat and could guarantee the run through casing size shortcoming.Therefore developed open hole packer horizontal well perforated pipe pressure break completion tubular column, it can realize horizontal well bore hole staged fracturing completion, greatly reduces construction cost, has avoided sliding sleeve to open construction risks such as difficulty simultaneously.Need not bore behind the pressing crack construction of the present invention and mill the interior latus rectum that just can guarantee the pipe string, be convenient to the production and the shutoff adjustment of interval.
Summary of the invention: the objective of the invention is to develop and a kind ofly can separate the stratum, can guarantee run through casing size again, be convenient to the open-hole horizontal well open hole packer of follow-up pressure break, water blockoff, water filling job execution and preset linker pressure break completion method at horizontal well.
The present invention is by realizing with lower device: this device by deliver tubing string, set tubing string, three times tubing strings of fracturing string are realized, wherein deliver tubing string by drilling rod, hanging packer, sleeve pipe, open hole packer, preset linker, float shoe is formed; Set tubing string by oil pipe, K344 packer, restriction choke, dead stifled etc. the composition; Fracturing string is made up of oil pipe, safety joint, centralizer, hydraulic anchor, K344 packer, pilot sandblaster, dead the blocking up of guiding; Above-mentioned technology realizes by following steps:
A, at first will deliver tubing string drilling rod, hanging packer, sleeve pipe, open hole packer, preset linker, float shoe connects successively, down to the horizontal well precalculated position;
B, secondly be lowered to successively oil pipe, K344 packer, restriction choke, the dead stifled tubing string that sets that connects, and restriction choke aimed at open hole packer and hanging packer, ground fluid injection then, restriction choke produces chock pressure difference, make left and right sides K344 packer setting, separate open hole packer, liquid comes out to enter in open hole packer and the hanging packer through the hole of restriction choke, open hole packer and hanging packer are set, put forward mode on utilizing at last and set open hole packer and hanging packer step by step, trip out after setting and set tubing string;
C, be lowered to successively the dead stifled fracturing string of the oil pipe, safety joint, centralizer, hydraulic anchor, K344 packer, pilot sandblaster, the guiding that connect then, after oil pipe carries and arrives the interior precalculated position of sleeve pipe under this fracturing string, sit well head, ground fluid injection then, the pilot sandblaster produces chock pressure difference and makes left and right sides K344 packer setting, separated oil layer section, liquid comes out to through the side opening of pilot sandblaster and presets linker and enter into the stratum, press off the stratum, upper lifting pipe post behind the intact interval of pressure break is finished the pressing crack construction of all intervals piecemeal.
Compared with the prior art the present invention has following advantage:
1) completion mode is simple, after open hole packer sets sealing, can be divided into several sections to the stratum.
2) latus rectum is big in the tubing string inner sleeve, and hop count is many, can carry out measure to certain interval arbitrarily, can significantly reduce cost.
Description of drawings: Fig. 1 is for delivering the tubular column structure sketch; Fig. 2 is a setting pipe rod structure sketch; Fig. 3 is the fracturing string structure diagram.
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing: the present invention is by realizing with lower device: this device by deliver tubing string, set tubing string, three times tubing strings of fracturing string are realized, wherein deliver tubing string by drilling rod 1, hanging packer 2, sleeve pipe 3, open hole packer 4, preset linker 5, float shoe 6 is formed; Set tubing string by oil pipe 7, K344 packer 8, restriction choke 9, extremely stifled 10 etc. form; Fracturing string is made up of oil pipe 11, safety joint 12, centralizer 13, hydraulic anchor 14, K344 packer 15, pilot sandblaster 16, guiding dead stifled 17; Above-mentioned technology realizes by following steps:
A, at first will deliver tubing string drilling rod 1, hanging packer 2, sleeve pipe 3, open hole packer 4, preset linker 5, float shoe 6 and connect successively, down to the horizontal well precalculated position; According to geologic requirements, with open hole packer 4 horizontal segment is divided into six well sections, there are six intervals to need following six of pressure break to preset linker, after putting in place under the tubing string, after giving up, hanging packer trips out drilling rod 1.
B, secondly be lowered to successively the oil pipe 7, K344 packer 8, the restriction choke 9 that connect, extremely stifled 10 set tubing string, and with restriction choke 9 aligning open hole packer 4 and hanging packers 2, ground fluid injection then, restriction choke 9 produces chock pressure difference, left and right sides K344 packer 8 is set, separate open hole packer 4, liquid is in open hole packer 4 and hanging packer 2 are come out to enter in the hole of restriction choke 9, open hole packer 4 and hanging packer 2 are set, put forward mode on utilizing at last and set open hole packer 4 and hanging packer 2 step by step, trip out after setting and set tubing string;
C, be lowered to the oil pipe 11 that connects successively then, safety joint 12, centralizer 13, hydraulic anchor 14, K344 packer 15, pilot sandblaster 16, dead stifled 17 fracturing strings of guiding, after oil pipe 11 carries and arrives sleeve pipe 3 interior precalculated positions under this fracturing string, sit well head, ground fluid injection then, pilot sandblaster 16 produces chock pressure difference sets left and right sides K344 packer 15, separated oil layer section, liquid comes out to through the side opening of pilot sandblaster 16 and presets linker 5 and enter into the stratum, press off the stratum, upper lifting pipe post behind the intact interval of pressure break, make this tool string advance to another interval and carry out pressure break, one-trip string just can be finished six sections pressure breaks like this.
