【摘要】：近年來,榆樹林油田集輸和注水系統(tǒng)結(jié)垢嚴重,影響了油田生產(chǎn)安全平穩(wěn)運行,大幅度增加了維修維護成本費用。主要問題表現(xiàn)為:一是集油管網(wǎng)結(jié)垢堵塞影響生產(chǎn)運行;二是加熱爐煙火管、盤管結(jié)垢導致爐效降低;三是注入水中較高含量的鈣、鎂離子,易引起井下管柱和地層產(chǎn)生結(jié)垢現(xiàn)象。針對該結(jié)垢問題,開展了一系列的理論與實驗研究,通過結(jié)垢狀況分析、化學劑篩選和現(xiàn)場跟蹤試驗等方面的綜合研究,取得了如下研究結(jié)果:(1)通過對榆樹林油田集輸摻水系統(tǒng)和供、注水系統(tǒng)結(jié)垢情況普查,結(jié)合水樣、垢樣分析及結(jié)垢機理分析,找出目前結(jié)垢狀況急需解決的問題。(2)從8種防垢單劑中篩選出性能較好的ATMP和HPMA,可作為基準物,初步檢驗成品防垢劑性能。單劑與成品對比表明:單一配方的產(chǎn)品,不能解決所有水樣的防垢問題。(3)通過對防垢劑與絮凝劑、破乳劑、殺菌劑的配伍性實驗,找到三類藥劑與防垢劑之間配合使用的方法和注意事項。(4)以防垢率大于80%為目標,通過室內(nèi)實驗、現(xiàn)場跟蹤檢測和藥量調(diào)整,制定出優(yōu)化的現(xiàn)場加藥制度。在此加藥制度下,注水系統(tǒng)總加藥量降低了28.5kg/d;集輸系統(tǒng)總加藥量降低了10.5kg/d。在新加藥制度下,降低加藥成本8.54萬元/年。
[Abstract]:In recent years, the scaling of gathering, transportation and water injection systems in Yushulin Oilfield has been serious, which has affected the safe and stable operation of oil field production and greatly increased the cost of maintenance and maintenance. The main problems are as follows: first, the fouling blockage of the oil collecting pipe network affects the production operation; second, the pyrotechnic tube of the reheating furnace, the fouling of the coil tube causes the furnace efficiency to be reduced; and the third is the injection of higher contents of calcium and magnesium ions in the water. It is easy to cause downhole pipe string and formation to scale. Aiming at this problem, a series of theoretical and experimental studies have been carried out, including comprehensive research on scaling condition analysis, chemical agent screening and field tracking test, etc. The following research results are obtained: (1) through the general survey of scale formation in the water collection and transportation system and water supply and water injection system in Yushulin Oilfield, combined with water sample, scale sample analysis and scaling mechanism analysis, To find out the problem that needs to be solved at present) ATMP and HPMA which have better performance can be selected from 8 kinds of anti-scaling agents and can be used as reference material to preliminarily test the performance of finished anti-scaling agents. The comparison of single agent and finished product shows that the single formula product can not solve the problem of scale prevention of all water samples. The compatibility experiment of scale inhibitor with flocculant, demulsifier and fungicide is carried out through the experiment of compatibility of scale inhibitor with flocculant, demulsifier and bactericide. To find out the method of cooperating use between three kinds of medicament and antiscaling agent and the attention item. (4) taking the scale prevention rate more than 80% as the target, through the indoor experiment, the field tracking detection and the medicine quantity adjustment, the optimized field dosing system is worked out. Under this system, the total dosages of water injection system decreased by 28.5 kg / d, and the total dosages of gathering and transportation systems decreased by 10.5kg / d. Under the new drug addition system, the cost of drug addition was reduced by 85400 yuan per year.
