Description

一种堵水用高凝稠油活化剂及油井堵水方法 Plugging one kind of activating agent with a high pour heavy oil well plugging method

技术领域 FIELD

[0001] 本发明涉及一种堵水用高凝稠油活化剂及油井堵水方法,属于油井堵水领域。 [0001] The present invention relates to a shutoff activator and a high pour heavy oil well plugging method, plugging wells belonging to the art.

背景技术 Background technique

[0002] 油田进入注水开发中后期,含水不断上升,产量快速递减。 [0002] oilfield water injection into the late development, the water rising, production declining fast. 受储层非均质性强或微裂缝发育影响,水淹、水窜、底水锥进严重。 Reservoir heterogeneity by strong or microfractures, development, flooding, channeling water, bottom water coning serious. 平面上水驱波及差异性大,纵向吸水不均,注入水沿水窜通道指进,导致水驱控制程度和动用程度低。 Sheung plane of the swept big difference, unevenness longitudinal absorbent, water channeling water along the injection passage into the finger, resulting in the use of water flooding low level and degree of control. 单纯通过调剖,措施效果不够理想,稳油控水难度大。 By simple profile, we measure the effect is not ideal, a large stable of oil and water control difficult. 因此,有必要采取“调堵结合”的工作思路。 Therefore, it is necessary to take the work of thinking "plugging combination".

[0003]目前常用的堵水技术大都是非选择性堵剂,对出水层明确、隔层大、井况好的油井,其效果比较好。 [0003] plugging technique most commonly used non-selective blocking agent, a clear aqueous layer, large compartment, good oil well conditions, the effect is better. 而对于隔层小、井况差、找水难度大的油井,特别是边水、底水和注入水层内突进,采用非选择性堵水,在堵水的同时也将油层堵死,对油层产生很大伤害。 For small compartment, a difference well conditions, great difficulty to find water wells, in particular the water side, bottom and water is injected into the inner aqueous layer was sudden, non-selective water shutoff, oil will be blocked at the same time water shutoff, for oil generated a lot of damage. 因此,选择性堵水技术应运而生。 Thus, selective plugging technique emerged.

[0004]目前选择性堵水技术主要以部分水解聚丙烯酰胺类、活化稠油类为主。 [0004] It selectively plugging technique mainly partially hydrolyzed polyacrylamides, activation of class-based heavy oil. 但聚丙烯酰胺类堵水剂受地层温度影响,成胶稳定性差,有效期短,而活化稠油堵水作为一项选择性好、对油层无损害的油井堵水技术,近年来受到广泛关注,该技术的关键问题在于优选合适的原油乳化剂,目前油井堵水用原油乳化剂主要是SP-80、LHK-1等油包水型乳化剂。 However, polyacrylamides plugging agent by the formation temperature, the difference between gelation stability, short period, and the activation of heavy oil as a selective water shutoff, no damage to the oil well plugging technique, attracted widespread attention in recent years, the key problem with this technique is that a suitable crude oil emulsifier is preferably present with the crude oil shutoff emulsifier mainly SP-80, LHK-1 and other water-in-oil emulsifier. CN1429885A、CN1760338A分别公开了一些原油乳化剂及其制备方法。 CN1429885A, CN1760338A disclose a method for preparing some of the oil and emulsifier. 目前公开的上述原油乳化剂的成分比较复杂、成本比较高或实际使用中的经济效益比较差。 Oil emulsifier component of the present disclosure is relatively complex, the cost is relatively high economic efficiency or poor in practical use.

[0005] CN102061153A、GAI12CN0369C分别公开了一种油井堵水用原油乳化剂及其制备方法,所述乳化剂的原料为二甲胺、环氧氯丙烷、油酸和水。 [0005] CN102061153A, GAI12CN0369C respectively discloses a well plugging oil with emulsifier and a preparation method, the emulsifier raw materials for dimethylamine, epichlorohydrin, oleic acid, and water. 然而通过室内研究发现,该乳化剂存在原料具有挥发性、易燃、有毒等问题,需要在反应釜内提前配制,配制过程剧烈放热,操作危险,且堵剂耐温性差,对油藏储层物性要求高,同时必须用清水或去离子配制,会出现在现场施工时原油在地面乳化,导致无法注入地层等问题。 However, through the indoor found starting material having a volatile, flammable, toxic and other problems of the emulsifier we need to be prepared in advance in the reactor, vigorously exothermic formulation process, hazardous operation, and poor blocking agent temperature of reservoir in high physical property requirements, and must be formulated with or deionized water, occur when the construction site emulsified oil on the ground, can not lead to the injection formation and the like problems.

[0006] 因此,有必要寻找一种环境友好、制备工艺简单、耐温性好、强度高、适应油藏类型范围广的原油活化剂来解决上述问题。 [0006] Accordingly, it is necessary to find an environmentally friendly, simple preparation process, good heat resistance, high strength, wide range of oil reservoir type activator to solve the above problems.
