Abstract
The invention relates to an oil-gas-water well energy-gathering composite perforation process method, which combines the built-in and the lower hanging type composite perforation process, wherein a joint and a lower ignition charge are arranged at the lower part of the original built-in composite perforation device, the lower ignition charge adopts an ignition mode of combining a core pipe and an ignition charge column, and the pressure value generated by the ignition charge is adjusted by adjusting the number of the ignition charge columns; when oil-water well perforation operation is carried out, a built-in composite perforator is utilized to perforate a target layer at first, then a lower fire hanging agent is ignited, and the stratum is continuously loaded to form secondary pressure impact, so that the aims of improving the length of a crack and improving the flow conductivity are fulfilled. The energy-gathering composite perforation process provided by the invention is easy to implement and reliable in operation, has the advantages of built-in and hanging-down perforation processes, can complement the defects of the built-in and hanging-down perforation processes, and can achieve the good effects of improving the pressure raising speed, prolonging the action time of gas pressure and being beneficial to crack extension.
Description
Technical field:
The present invention relates to a kind of process that is used for the perforating job of oilfield well.
Background technology:
Perforating job is an important step in oilfield well completion and the manufacturing process.Composite gun perforation is that the gas that produces by powder burning in the perforating job process carries out pressure break to the stratum around the pit shaft and makes the seam effect, annotates to adopt and tells on to improve oil-water well.According to the action effect analysis of power, adopt production effect to improve the oil-water well notes.Action effect analysis according to power, the rate of rise of gas helps the generation in crack soon, action time is long more favourable more to fracture extension, and still, the on-the-spot at present built-in and following hanging two kinds of composite gun perforation process that adopt usually all can't satisfy the requirement of this two aspect simultaneously.
Summary of the invention:
The object of the present invention is to provide a kind of built-in and following hanging composite gun perforation process advantage but also can remedy both sides' deficiency, can prolong the gas pressure oil-water well energy-gathering composite perforating process of action time separately that not only can keep.
Technical scheme of the present invention is as follows: this kind energy-gathering composite perforating technology is with built-in and following the two use in conjunction of hanging composite gun perforation process, original built-in composite perforator bottom field joint and under the medicine of being furious, the medicine of being furious down adopts the sparking mode of core pipe and the combination of igniting powder column, regulates the force value that gunpowder produces by point of adjustment stick quantity; During the oil-water well perforating job, utilize built-in composite perforator at first to the target zone perforation, the medicine of being furious that ignites down then continues to load to the stratum, forms secondary pressure and impacts, thereby reach the purpose that improves fracture length and flow conductivity.
Energy-gathering composite perforating technology provided by the invention is easy to implement, reliable operation, the advantage that this technology has built-in and following hanging gun perforation process concurrently again can complementary its weak point, utilizes it to reach and improves the rate of rise and prolong gas pressure action time, help the good result of fracture extension.
Description of drawings:
The gun perforation process pipe string structure schematic diagram that accompanying drawing adopts for the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present invention is illustrated.
As shown in the figure, the gun perforation process pipe string that adopts during the invention process adopts cable transmission, from top to bottom for built-in perforator 1, joint 2, be furious medicine 3 and screen casing 4 down, wherein, the medicine 3 of being furious down is arranged in the screen casing 4.
Embodiment: 3365 meters of 20 well well depths are breathed out in certain oil field, adopt 76 rifles 76 to play cumulative composite cable transmission means perforation, cascode is opened 32.8 meters, 47 tons of day production fluids, 42 tons of day produce oils, 2540 cubic metres of daily gas, effect are better than adopting the offset well Ha20-1Jing (11.2 tons of day production fluids, 5.6 tons of day produce oils) of conventional gun perforation process greatly.
Claims (1)
1, a kind of oil gas water well energy-gathering composite perforating process, it is characterized in that: this kind energy-gathering composite perforating process is with built-in and following the two use in conjunction of hanging composite gun perforation process, original built-in composite perforator bottom field joint and under the medicine of being furious, the medicine of being furious down adopts the sparking mode of core pipe and the combination of igniting powder column, regulates the force value that gunpowder produces by point of adjustment stick quantity; During the oil-water well perforating job, utilize built-in composite perforator at first to the target zone perforation, the medicine of being furious that ignites down then continues to load to the stratum, forms secondary pressure and impacts, thereby reach the purpose that improves fracture length and flow conductivity.
