【正文】 uction always leads to low yield, high cost, high risk. In resent years, plicated structural wells, including sidetracking wells, horizontal wells, branched wells, etc., have been studied and developed in Liaohe oilfield. Through the application of these plicated structural wells in super heavy oil reservoir, low permeability reservoir, thin heavy reservoir, a very good result was obtained, improving oil recovery effectively, reducing running cost per ton. In addition, some stimulation treatment technologies have also been developed and adopted, such as sand control, high temperature injection profile modification, water finding and block off, oil production by using gases. In this paper, the developments and applications of the plicated structural wells and the stimulation treatment technologies for difficulttoproduce reserve are presented, and these research results will have some effects on the production of other similar difficulttoproduce reserve.Keywords: Liaohe oilfield。此外，在油井增油技術(shù)方面也取得突破，防砂、高溫調(diào)剖、找堵水、氣體采油技術(shù)等都進(jìn)一步完善和應(yīng)用。遼河油區(qū)難采儲(chǔ)量開(kāi)采技術(shù)發(fā)展?fàn)顩r及應(yīng)用王 旭 賈海燕（遼河石油勘探局工程技術(shù)研究院 遼寧盤(pán)錦 124010） 摘要：隨著遼河油區(qū)勘探開(kāi)發(fā)程度的不斷加深，難采、難動(dòng)用區(qū)塊的開(kāi)發(fā)已成為油田穩(wěn)產(chǎn)中不容忽視的問(wèn)題，實(shí)際情況表明，這些難采區(qū)塊分別存在著高凝、低滲、出砂、海上稠油開(kāi)采等技術(shù)困難，具有低產(chǎn)能、投資高、風(fēng)險(xiǎn)大的特點(diǎn)。經(jīng)過(guò)多年的持續(xù)技術(shù)攻關(guān)和實(shí)踐，遼河油區(qū)目前已經(jīng)陸續(xù)開(kāi)發(fā)了側(cè)鉆井、水平井、分支井等特殊工藝井鉆完井技術(shù)及配套技術(shù)，廣泛應(yīng)用于超稠油油藏、低滲透油藏、薄層稠油油藏開(kāi)發(fā)，極大提高了難采儲(chǔ)量動(dòng)用程度，降低噸油生產(chǎn)成本，取得良好的效果。本文重點(diǎn)介紹了特殊工藝井技術(shù)和油井增油技術(shù)在難采油藏開(kāi)發(fā)中的發(fā)展?fàn)顩r及應(yīng)用，希望對(duì)其它油區(qū)類(lèi)似油藏的開(kāi)發(fā)起到借鑒作用。 difficulttoproduce reserve。 stimulation treatment technologies?！熬盼濉?“十五”期間，針對(duì)難采儲(chǔ)量油藏特點(diǎn)，遼河油區(qū)廣泛調(diào)研與引進(jìn)國(guó)內(nèi)外先進(jìn)鉆采技術(shù)，通過(guò)自身研發(fā)、試驗(yàn)形成了一系列集鉆井、完井、采油等相配套的技術(shù)，提高了遼河油區(qū)難采儲(chǔ)量的開(kāi)發(fā)水平，為油田穩(wěn)產(chǎn)提供了有力的技術(shù)支持。1 遼河油區(qū)難采儲(chǔ)量基本概況從勘探開(kāi)發(fā)區(qū)域上看，遼河油區(qū)陸上動(dòng)用程度最高，外圍次之，最低的是灘海，目前動(dòng)用程度較低的難采區(qū)塊主要是超稠油、深層普通稠油和淺層高凝油，其中相當(dāng)大一部分是由于技術(shù)經(jīng)濟(jì)等因素制約難以實(shí)現(xiàn)有效開(kāi)發(fā)，形成未動(dòng)用難采儲(chǔ)量，具有“低、深、難、稠、小”的特點(diǎn)。104t， km2，石油地質(zhì)儲(chǔ)量48549205。 難采儲(chǔ)量區(qū)塊類(lèi)型及特點(diǎn)根據(jù)各油藏特點(diǎn)，把
