X-5井为D-X气田一口水平调整井,目的层D-X凹陷带X区块BH组B1层,为东倾单斜构造之局部断背斜构造。区块有效孔隙度较低,渗透能力差,是典型的低渗透油气藏。因钻井期间泥浆侵入、地层粘土水化膨胀及水锁等因素影响,X-5井完钻后通过气举返排诱喷无法获得理想产能。利用连续油管解堵增产技术对X-5井进行增产解堵,解除低渗储层水锁和在钻完井过程中的综合性堵塞伤害,恢复近井地带的导流能力,达到增产、稳产目的。
The X-5 well is a horizontal adjustment well in the D-X gas field. The D-X sag in the target zone is the B1 layer of the BH block in X block, and is a partial faulted anticline structure with east-dip monoclinic structure. The low effective porosity and poor permeability of the block are typical low-permeability reservoirs. Due to mud intrusion during drilling, hydration and expansion of clay in the stratum, water lock and other factors, X-5 well can not get the ideal capacity after drilling through gas lift and return row induction. The use of coiled tubing plugging and stimulation technology to increase the production of X-5 wells plugging, lifting the low-permeability reservoir water lock and integrated in the process of drilling and completion of the plugging damage, recovery near the wellbore of the diversion capabilities, to increase production and stable production purpose.
